What version of ubuntu are you using? You tried to add the gusty repository which was from something like ubuntu 7.10. So open the dialog where you can change your software sources (depends on which ubuntu youre using).

later on i understood how remove medibuntu from the list, but since i tried to put sudo apt-get update, it asked me a password that it was impossible to insert why ?
